PI2001

PI2001 Cool-ORing Universal Active ORing Controller IC Description The PI2001 Cool-ORing solution is a universal high-speed Active ORing controller IC designed for use with N-channel MOSFETs in redundant power system architectures. The PI2001 Cool-ORing controller enables an extremely low power loss solution with fast dynamic response to fault conditions, critical for high availability systems. The PI2001 controls single or parallel MOSFETs to address Active ORing applications protecting against power source failures. The PI2001 can be used in either high-side or low-side Active ORing applications and a master/slave feature allows the paralleling of IC/MOSFET chipsets for high current Active ORing. The gate drive output turns the MOSFET on in normal steady state operation, while achieving highspeed turn-off during input power source fault conditions, that cause reverse current flow, with auto-reset once the fault clears. The MOSFET drain-to-source voltage is monitored to detect normal forward, excessive forward, light load and reverse current flow. The PI2001 provides an active low fault flag output to the system during excessive forward current, reverse current, light load, overvoltage, under-voltage and over-temperature fault conditions. There is an internal shunt regulator at www.DataSheet4U.com the VC input for high voltage applications and the under-voltage and over-voltage thresholds are programmable via external resistor dividers.
